[Does Global Tilted Plane ( GlobInc) results be affected because of multiple orientation of solar panels?]

Hi, may i ask if having different orientation of solar panels affect the result of GlobInc.

I have run 3 capacity, 80kWp, 100kWp and 200kWp grid tied system. 80kWp and 100kWp solar panels orientation is both facing the same direction (1 orientation) and so happen to have the same result of GLOBINC, while the 200kWp system has two orientations of panels and the result of GLOBINC is different from the two other systems.GLOBINC became lower for the 200kWp.

I hope you can explain to me why this happens and I can easily understand.

Thank you.

Thank you for this. 

 

 

Does it also mean if I have measured N= 42.2° , SE 132.2°

The azimuth southern facing will be 0° + 42.2° = 42.2°  ?

Attached here i have measure through solmetric roof azimuth tools. If the location was in northern hemisphere, how can invert the measured degrees in line with PVsyst system. Thank you.

Thank you for this. Can you kindly help me to understand it more given the following examples.

If the following roof facing :

1. South - 177 degree

2. East - 95.3 degree

3. West - 275 degree

What degree should be input on the plane orientation?

As you have mention - South facing which have 180degree is equivalent to 0 degrees azimuth in the Northern Hemisphere area

On The Second way you have mentioned, that plane azimuth is required. If my panels facing south, what degree angle should be input, considering that our location is in the northern hemisphere?

I needed to export hourly irradiance data including the Global Tilted Plane. Kindly explain how to understand the Plane Azimuth degree. What angle degree should be input if solar panels are tilted facing south?
